Cyprian Iwuaba Sr. was born and raised in Nigeria. He lived in Cameroon during the Nigerian civil war. upon his return, there was an outbreak of a great revival in Nigeria. He was a child born out of that out pouring of the Holy Spirit at age seventeen. Like he always says, "I saw the fire of God and I knew the difference" he was part of that fire-band. Early on, he became the chorus leader and interpreter for visiting missionaries. At age twenty, he started teaching Sunday school and later became the Sunday School Superintendent Years later, he had a call of God in his life into a full time ministry, although he resisted it and prayed rather to be a supporter of the ministry.

Pastor Cyprian was ordained in 1979. After his ordination, he attended Morris Cerullo School of Ministry in San Diego California, in 1980. then he returned back to Nigeria to continue with the Film Ministry he had founded with his friend. After surrendering to God's call upon his life in 1982, he served as assistant pastor to the head quarter church of Grace of God Mission. From then on, there was an urge in him to further his education in theology.

Pastor Cyprian returned to San Diego in December of 1985, studied and graduated from Southern California Bible College. Next, he attended Tribune Biblical University Kelso, Washington where he obtained master of theology and Doctor of Christian counseling. he also served as an assistant pastor at mount Tabor Missionary Baptist Church from 1986-1993.

In 1994, he started a church with his friends at his living room where he was elected the lead pastor. That ministry gave birth to Abundant Grace Christian Center in 2003.

He is the loving husband and friend of Dr. Chinazom B. Iwuaba. Together they have been married about forty years by the abundant grace of God. And in his union, God has blessed them with eight children and eight grandchildren.
